병렬 연결된 다수 대 계통연계형 인버터를 위한 단독운전 방지 기법 = The Anti-islanding Scheme for a Number of Grid-connected Inverters Under Parallel Operation

다국어 초록 (Multilingual Abstract)

Anti-islanding scheme of grid-connected inverter is a key function of standards compliance, since unintentional islanding results in safety hazards, reliability, and many other issues. Therefore, many anti-islanding schemes have been researched, however, most of them have problems, which deteriorate performance of islanding detection under parallel-operation. Therefore, this paper proves the reason of problems and proposes a new anti-islanding scheme that has precise islanding detection under parallel-operation in single-phase and three-phase system. Finally, both simulation and experimental result validate the proposed scheme.
